Plastic bottles are shaping the world by connecting marketing networks across the globe. Due to evolving polymer materials, delivering products in fresh conditions across states, countries, and overseas is possible. Proper packaging also helps the enclosed product last longer. Moreover, it holds a significant advantage over metal or glass containers. Plastic bottles are a more durable and cost-effective alternative and hence most preferred to store various liquids, soft drinks, juices, etc.

Due to their molecular composition, plastics are light in weight and can be moulded into any shape or size based on requirements. A well-designed PET bottle can help optimise storage and stacking due to convenience and proper packaging. PET bottle's primary purpose is to maintain the freshness of the product within. However, if the bottle fails to hold its content, this may lead to significant loss and damage to the brand's reputation. Top load testing can accurately determine the strength and capability of the sample, helping manufacturers deliver PET containers that assure safe product delivery.

What Is Top Load Testing

Top load testing is a functional test that helps manufacturers or Users verify PET bottle seal and holding capacity. The quality of any product is affected by the product it is made up of. Polymers have multiple qualities that offer varying degrees of strength and durability. You can use a top load testing instrument to determine the force a PET bottle can withstand without showing any signs of distortion. The various advanced microprocessor-based equipment in the marketplace delivers high-level precision in test results.

How Does Top Load Tester Work?

The top load test is used to determine the performance of PET bottles. The equipment is designed to check the load-bearing capacity of the instrument. Therefore, manufacturers can subject the PET containers to varying degrees of pressure using the equipment to ensure better quality performance. Following is a step-by-step guide to performing load testing on a sample PET bottle followed by most of the automatic top laid testers in the market.

Step 1: The PET bottle specimen is placed over the compression plates. The instrument is designed to ensure the sample stays in place during the test.

Step 2: The instrument has strong compression plates to deliver uniform pressure on the sample bottle. Advanced top-load test instruments offer both automatic as well as manual testing. Manufacturers can choose the mode based on their requirements.

Step 3: Adjust the settings on the instruments to initiate the mode. In the case of automatic, the users can observe the specimen while the instrument applies gradual pressure until the slightest signs of distortion. In the manual case, the manufacturer may subject the sample to the required force to safely deliver it to the end users.

Final Thoughts

Choose an advanced top load tester that is user-friendly and capable of performing automatic functions. Pacorr is one of the leading producers of testing instruments. They have a user-friendly tabletop model of a top load tester that can automatically record top load peak value. It is built with a heavy-duty frame to ensure long-run performance and protection against rusting. The manual mode enables the tester to subject the sample with variable frequency using easy-to-use speed controls.
